MetabolomicsCDK4/6 inhibitor-mediated cell overgrowth triggers an osmotic stress response and chronic p38MAPK activation to promote long-term cell cycle arrest

Cell size and the cell cycle are intrinsically coupled and abnormal increases in cell size are associated with senescence and permanent cell cycle arrest. The mechanism by which overgrowth primes cells to withdraw from the cell cycle remains unknown. We investigate this here using CDK4/6 inhibito...

MetabolomicsX-ray Irradiation Suppresses Keloid Growth by Inducing G2/M Arrest via the Phytosphingosine-KIF20A Axis
Keloid radiotherapy is clinically effective but has an incomplete underlying molecular mechanism and limited accessibility; we used X-ray exposure to identify effector pathways replicating its antifibrotic benefits without further radiation. After collecting patient keloid samples, primary human kel...

TranscriptomicsMitotic stress is an integral part of the oncogene-induced senescence program that promotes multinucleation and cell cycle arrest
Oncogene-induced senescence (OIS) is a tumor suppression mechanism that blocks cell proliferation in response to oncogenic signalling. OIS is frequently accompanied by multinucleation; however, the origin of this is unknown. Here we show that multinucleate OIS cells originated mostly from failed mit...

ProteomicsCAMK2D recruits RNF8-MAD2 complex to RNA splicing proteins for mitotic checkpoint activation in GBM
Glioblastoma (GBM) is a lethal brain tumor with remarkable intra-tumoral heterogeneity and therapeutic resistance which is linked to glioma stem cell (GSC). GSC contains unstable genome and elevated genomic instability could impair GSC self-renewal and tumorigenicity. In addition, GSC displays great...

TranscriptomicsDMRT6 coordinates the transition between mitotic and meiotic developmental programs during mamalian spermatogenesis
In mammals, a key transition in spermatogenesis is the exit from spermatogonial differentiation and mitotic proliferation and the entry into spermatocyte differentiation and meiosis. Although several genes that regulate this transition have been identified, how it is controlled and coordinated remai...

ProteomicsNuclear release of eIF1 globally increases stringency of start codon selection to preserve mitotic arrest physiology
Regulated start codon selection has the potential to reshape the proteome through the differential production of uORFs, canonical proteins, and alternative translational isoforms. However, conditions under which start codon selection is altered remain poorly defined. Here, using transcriptome-wide t...

TranscriptomicsRegulation of male germ cell cycle arrest and differentiation by DND1 is modulated by genetic background
Transcriptional profiling of E14.5 XY germ cells (marked with Oct4-EGFP transgene) from two strain backgrounds (C57BL/6J and 129S1/SvImJ) that differ in their susceptibility to testicular teratomas. Two condition experiment. For each sample, Oct4-EGFP+ germ cells from all XY embyos within a litter w...

ProteomicsProteomics profiling of mitotic arrest by transcriptional silencing of the Cdc20 homolog slp1 in fission yeast
Depletion of the APC/C activator Cdc20 arrests cells in metaphase with high levels of the mitotic cyclin (Cyclin B) and the Separase inhibitor Securin. In mammalian cells this arrest has been exploited for the treatment of cancer with drugs that engage the spindle assembly checkpoint and, recently, ...

TranscriptomicsTranscription profiling of human p53+ and p53- fibroblasts treated with arsenite reveals exit from arsenite-induced mitotic arrest is p53 dependent
Microarray data from G2-synchronized p53(+) and p53(-) fibroblasts before and after 3 h release from cell cycle blockade in the presence of 5 uM sodium arsenite. Experiment Overall Design: Cells expressing p53 from a tet-off regulated construct were synchronized in G2 with a two-step procedure using...
